Question about Cars & Trucks
The code means the EBCM (electronic brake control module) is receiving faulty data from other modules or is faulty itself. If you are asking what has failed, IDK. This issue requires diagnostics. If you want to. Write back with Year Make and Model. I suspect this is a GM vehicle. Please let me know if there is anything else.

When the PCM detects a continuous open, short to ground or short to voltage in the PC solenoid valve circuit, then DTC P0748 sets. DTC P0748 is a type C DTC.
PC - pressure control solenoid .
The powertrain control module (PCM) uses the pressure control (PC) solenoid valve in order to regulate the transmission line pressure. The PC solenoid valve consists of an electrical connector, a coil, an armature, a regulating spring, and a poppet valve. The PC solenoid valve is attached to the control valve body. The PCM compares TP voltage, fluid temperature, gear states, and other inputs in order to determine the line pressure appropriate for a given load. The PCM regulates the pressure by applying a varying amperage to the PC solenoid valve. The applied amperage varies from 0.1 amps for maximum line pressure to 1.1 amps for minimum line pressure. The PCM then monitors the amperage at the return line.
System Disabled Information Stored
DTC C0561 in Antilock Brake System This code is a result of the transmission code .
The electronic brake control module (EBCM) disables the traction control when other electronic control modules set DTCs for components that effect the operation of the traction control system.

SOURCE: 2005 sts caddy when abs traction Control System and stability system lights flash. Loses power until shut off ignition and turn back on. No lights on now but had scanned and got codes co242 and co561
These codes mean there is an intermittent fault in the Electronic Brake Control Module (EBCM) or with a signal from one of the other modules feeding it (such as the ABS system).
Intermittents like this occur once in a while with vehicle computers not starting correctly or inter-communications network problems (due to data timing, electrical noise issues, etc.) and will usually disappear. However, if it continues, this is not something you should attempt to fix yourself - visit a dealer, but hang on tight to your wallet.
